Method Detail

getExpression

public <any> getExpression()

Returns the expression to be tested against the list of values.

Returns:

expression

findRootAndParameters

public void findRootAndParameters(CommonAbstractCriteriaImpl query)

Specified by:

findRootAndParameters in interface InternalSelection

Overrides:

findRootAndParameters in class FunctionExpressionImpl<java.lang.Boolean>

isPredicate

public boolean isPredicate()

Specified by:

isPredicate in interface InternalExpression

Overrides:

isPredicate in class CompoundExpressionImpl

value

public <any> value(T value)

Add to list of values to be tested against.

Parameters:

value - value

Returns:

in predicate

value

public <any> value(<any> value)

Add to list of values to be tested against.

Parameters:

value - expression

Returns:

in predicate

setParentNode

public void setParentNode(org.eclipse.persistence.expressions.Expression parentNode)

This method is used to store what will be the parent EclipseLink expression in the case the tree needs to be altered. Currently used for In.

Overrides:

setParentNode in class CompoundExpressionImpl

not

public Predicate not()

Description copied from class: CompoundExpressionImpl

Apply negation to the predicate.

Overrides:

not in class CompoundExpressionImpl

Returns:

the negated predicate
