Uses of LogicalStatement in org.dspace.content.logic

Subinterfaces of LogicalStatement in org.dspace.content.logic

Modifier and Type	Interface	Description
interface	Filter	The interface for Filter currently doesn't add anything to LogicalStatement but inherits from it just to keep naming / reflection clean, and in case Filters should do anything additional in future.

Classes in org.dspace.content.logic that implement LogicalStatement

Modifier and Type	Class	Description
class	DefaultFilter	The default filter, a very simple implementation of Filter / LogicalStatement The idea is to have this as a wrapper / root class for all logical operations, so it takes a single statement as a property (unlike an operator) and takes no parameters (unlike a condition)
class	TrueFilter	Extremely simple filter that always returns true!

Methods in org.dspace.content.logic with parameters of type LogicalStatement

Modifier and Type	Method	Description
void	DefaultFilter.setStatement(LogicalStatement statement)	Set statement from Spring configuration in item-filters.xml Be aware that this is singular not plural.

Uses of LogicalStatement in org.dspace.content.logic.condition

Subinterfaces of LogicalStatement in org.dspace.content.logic.condition

Modifier and Type	Interface	Description
interface	Condition	The Condition interface A condition is one logical statement testing an item for any idea.

Classes in org.dspace.content.logic.condition that implement LogicalStatement

Modifier and Type	Class	Description
class	AbstractCondition	Abstract class for conditions, to implement the basic getter and setter parameters
class	BitstreamCountCondition	A condition to evaluate an item based on how many bitstreams it has in a particular bundle
class	InCollectionCondition	A condition that accepts a list of collection handles and returns true if the item belongs to any of them.
class	InCommunityCondition	A condition that accepts a list of community handles and returns true if the item belongs to any of them.
class	IsArchivedCondition	A condition that returns true if the item is archived
class	IsWithdrawnCondition	A condition that returns true if the item is withdrawn
class	MetadataValueMatchCondition	A condition that returns true if a pattern (regex) matches any value in a given metadata field
class	MetadataValuesMatchCondition	A condition that returns true if any pattern in a list of patterns matches any value in a given metadata field
class	ReadableByGroupCondition	A condition that accepts a group and action parameter and returns true if the group can perform the action on a given item

Uses of LogicalStatement in org.dspace.content.logic.operator

Classes in org.dspace.content.logic.operator that implement LogicalStatement

Modifier and Type	Class	Description
class	AbstractOperator	Abstract class for an operator.
class	And	An operator that implements AND by evaluating sub-statements and only returning true if all sub-statements return true
class	Nand	An operator that implements NAND by negating an AND operation
class	Nor	An operator that implements NOR by negating an OR operation.
class	Not	An operator that implements NOT by simply negating a statement Note that this operator doesn't actually implement the 'AbstractOperator' interface because we only want one sub-statement.
class	Or	An operator that implements OR by evaluating sub-statements and returns true if one or more sub-statements return true

Modifier and Type	Method	Description
LogicalStatement	Not.getStatements()	Get sub-statement (note: singular!
