Method Detail

getSpecification

public NakedObjectSpecification getSpecification()

getAdaptedClass

public final java.lang.Class<?> getAdaptedClass()

The underlying class that has been adapted.

Used to determine whether an empty string can be parsed, (for primitive types a non-null entry is required, see mustHaveEntry()), and potentially useful for debugging.

alwaysReplace

public boolean alwaysReplace()

We don't replace any (none no-op) facets.

For example, if there is already a PropertyDefaultFacet then we shouldn't replace it.

Specified by:

alwaysReplace in interface Facet

Overrides:

alwaysReplace in class FacetAbstract

getEncoderDecoder

public EncoderDecoder getEncoderDecoder()

Specified by:

getEncoderDecoder in interface ValueSemanticsProvider

getParser

public Parser getParser()

Specified by:

getParser in interface ValueSemanticsProvider

getDefaultsProvider

public DefaultsProvider getDefaultsProvider()

Specified by:

getDefaultsProvider in interface ValueSemanticsProvider

isEqualByContent

public boolean isEqualByContent()

Specified by:

isEqualByContent in interface ValueSemanticsProvider

isImmutable

public boolean isImmutable()

Specified by:

isImmutable in interface ValueSemanticsProvider

parseTextEntry

public java.lang.Object parseTextEntry(java.lang.Object context,
                                       java.lang.String entry)

Specified by:

parseTextEntry in interface Parser

doParse

protected abstract java.lang.Object doParse(java.lang.Object original,
                                            java.lang.String entry)

Parameters:

original - - the underlying object, or null.

entry - - the proposed new object, as a string representation to be parsed

displayTitleOf

public java.lang.String displayTitleOf(java.lang.Object object)

Specified by:

displayTitleOf in interface Parser

parseableTitleOf

public java.lang.String parseableTitleOf(java.lang.Object existing)

Defaults to displayTitleOf(Object).

Specified by:

parseableTitleOf in interface Parser

titleString

protected java.lang.String titleString(java.text.Format formatter,
                                       java.lang.Object object)

titleString

protected abstract java.lang.String titleString(java.lang.Object object)

Return a string representation of aforesaid object.

typicalLength

public final int typicalLength()

Specified by:

typicalLength in interface Parser

getDefaultValue

Specified by:

getDefaultValue in interface DefaultsProvider

toEncodedString

public java.lang.String toEncodedString(java.lang.Object object)

Specified by:
