Interface OMRSRepositoryHelper

All Superinterfaces:

OMRSRepositoryPropertiesHelper

public interface OMRSRepositoryHelper
extends OMRSRepositoryPropertiesHelper

OMRSRepositoryHelper provides methods to repository connectors and repository event mappers to help them build valid type definitions (TypeDefs), entities and relationships. It is a facade to the repository content manager which holds an in memory cache of all the active TypeDefs in the local server. OMRSRepositoryHelper's purpose is to create an object that the repository connectors and event mappers can create, use and discard without needing to know how to connect to the repository content manager.

getExactMatchRegex

String getExactMatchRegex(String searchString)

Retrieve an escaped version of the provided string that can be passed to methods that expect regular expressions, without being interpreted as a regular expression (i.e. the returned string will be interpreted as a literal -- used to find an exact match of the string, irrespective of whether it contains characters that may have special meanings to regular expressions). Note that usage of the string by methods that cannot handle regular expressions should first un-escape the string using the getUnqualifiedLiteralString helper method.

Parameters:

searchString - - the string to escape to avoid being interpreted as a regular expression

Returns:

string that is interpreted literally rather than as a regular expression

See Also:

isExactMatchRegex(String), getUnqualifiedLiteralString(String)

isExactMatchRegex

boolean isExactMatchRegex(String searchString)

Indicates whether the provided string should be treated as an exact match (true) or any other regular expression (false). Note that this method relies on the use of the getExactMatchRegex helper method having been used to qualify a string when it should be treated as a literal. That is, this method relies on the presence of the escape sequences used by Java's Pattern.quote() method. The method is not intended to work on all strings in general to arbitrarily detect whether they might be a regular expression or not. Primarily a helper method for methods that do not directly handle regular expressions (for those it should be possible to just directly use the string as-is and it will be correctly interpreted).

Parameters:

searchString - - the string to check whether it should be interpreted literally or as as a regular expression

Returns:

true if the provided string should be interpreted literally, false if it should be interpreted as a regex

See Also:

getExactMatchRegex(String), getUnqualifiedLiteralString(String)

getContainsRegex

String getContainsRegex(String searchString)

Retrieve an escaped version of the provided string that can be passed to methods that expect regular expressions, to search for the string with a "contains" semantic. The passed string will NOT be treated as a regular expression; if you intend to use both a "contains" semantic and a regular expression within the string, simply construct your own regular expression directly (not with this helper method). Note that usage of the returned string by methods that cannot handle regular expressions should first un-escape the returned string using the getUnqualifiedLiteralString helper method.

Parameters:

searchString - - the string to escape to avoid being interpreted as a regular expression, but also wrap to obtain a "contains" semantic

Returns:

string that is interpreted literally, wrapped for a "contains" semantic

See Also:

isContainsRegex(String), getUnqualifiedLiteralString(String)

isContainsRegex

boolean isContainsRegex(String searchString)

Indicates whether the provided string should be treated as a simple "contains" regular expression (true) or any other regular expression (false). Note that this method relies on the use of the getContainsRegex helper method having been used to qualify a string when it should be treated primarily as a literal with only very basic "contains" wrapping. Primarily a helper method for methods that do not directly handle regular expressions (for those it should be possible to just directly use the string as-is and it will be correctly interpreted).

Parameters:

searchString - - the string to check whether it should be interpreted as a simple "contains"

Returns:

true if the provided string should be interpreted as a simple "contains", false if it should be interpreted as a full regex

See Also:

getContainsRegex(String), getUnqualifiedLiteralString(String)

getStartsWithRegex

String getStartsWithRegex(String searchString)

Retrieve an escaped version of the provided string that can be passed to methods that expect regular expressions, to search for the string with a "startswith" semantic. The passed string will NOT be treated as a regular expression; if you intend to use both a "startswith" semantic and a regular expression within the string, simply construct your own regular expression directly (not with this helper method). Note that usage of the returned string by methods that cannot handle regular expressions should first un-escape the returned string using the getUnqualifiedLiteralString helper method.

Parameters:

searchString - - the string to escape to avoid being interpreted as a regular expression, but also wrap to obtain a "startswith" semantic

Returns:

string that is interpreted literally, wrapped for a "startswith" semantic

See Also:

isStartsWithRegex(String), getUnqualifiedLiteralString(String)

isStartsWithRegex

boolean isStartsWithRegex(String searchString)

Indicates whether the provided string should be treated as a simple "startswith" regular expression (true) or any other regular expression (false). Note that this method relies on the use of the getStartsWithRegex helper method having been used to qualify a string when it should be treated primarily as a literal with only very basic "startswith" wrapping. Primarily a helper method for methods that do not directly handle regular expressions (for those it should be possible to just directly use the string as-is and it will be correctly interpreted).

Parameters:

searchString - - the string to check whether it should be interpreted as a simple "startswith"

Returns:

true if the provided string should be interpreted as a simple "startswith", false if it should be interpreted as a full regex

See Also:

getStartsWithRegex(String), getUnqualifiedLiteralString(String)

getEndsWithRegex

String getEndsWithRegex(String searchString)

Retrieve an escaped version of the provided string that can be passed to methods that expect regular expressions, to search for the string with an "endswith" semantic. The passed string will NOT be treated as a regular expression; if you intend to use both a "endswith" semantic and a regular expression within the string, simply construct your own regular expression directly (not with this helper method). Note that usage of the returned string by methods that cannot handle regular expressions should first un-escape the returned string using the getUnqualifiedLiteralString helper method.

Parameters:

searchString - - the string to escape to avoid being interpreted as a regular expression, but also wrap to obtain an "endswith" semantic

Returns:

string that is interpreted literally, wrapped for an "endswith" semantic

See Also:

isEndsWithRegex(String), getUnqualifiedLiteralString(String)

isEndsWithRegex

boolean isEndsWithRegex(String searchString)

Indicates whether the provided string should be treated as a simple "endswith" regular expression (true) or any other regular expression (false). Note that this method relies on the use of the getEndsWithRegex helper method having been used to qualify a string when it should be treated primarily as a literal with only very basic "endswith" wrapping. Primarily a helper method for methods that do not directly handle regular expressions (for those it should be possible to just directly use the string as-is and it will be correctly interpreted).

Parameters:

searchString - - the string to check whether it should be interpreted as a simple "endswith"

Returns:

true if the provided string should be interpreted as a simple "endswith", false if it should be interpreted as a full regex

See Also:

getEndsWithRegex(String), getUnqualifiedLiteralString(String)

getUnqualifiedLiteralString

String getUnqualifiedLiteralString(String searchString)

Retrieve an unescaped version of the provided string that can be treated as a literal (not a regular expression). Primarily a helper method for methods that do not directly leverage regular expressions: so that they have a string they can treat as a literal without needing to un-escape the regex-meaningful characters injected by the various getXYZRegex helper methods. For example, this will translate the input of '.*\Qmy-search-string\E.*' into a return value of 'my-search-string'.

Parameters:

searchString - - the (potentially) wrapped and escaped string to un-escape and un-wrap

Returns:

the un-escaped, un-wrapped literal string
