Constructor Detail

AbstractCaseExpressionStateObjectBuilder

protected AbstractCaseExpressionStateObjectBuilder(StateObject parent)

Creates a new AbstractCaseExpressionStateObjectBuilder.

Parameters:

parent - The parent of the CASE expression to build, which is only required when a JPQL fragment needs to be parsed

Method Detail

buildStateObject

public CaseExpressionStateObject buildStateObject()

Creates the actual state object based on the information this builder gathered.

Specified by:

buildStateObject in interface ICaseExpressionStateObjectBuilder

Returns:

The newly created CaseExpressionStateObject

when

public ICaseExpressionStateObjectBuilder when(ICaseExpressionStateObjectBuilder when,
                                              ICaseExpressionStateObjectBuilder then)

Creates a single WHEN expression.

Specified by:

when in interface ICaseExpressionStateObjectBuilder

Parameters:

when - The WHEN expression

then - The THEN expression

Returns:

This builder
