JPQLQueryBuilder2_0

public JPQLQueryBuilder2_0()

Creates a new JPQLQueryBuilder2_0.

Method Detail

buildStateObjectBuilder

protected DefaultStateObjectBuilder buildStateObjectBuilder()

Creates the builder that creates the StateObject for each Expression.

Specified by:

buildStateObjectBuilder in class AbstractJPQLQueryBuilder

Returns:

The builder that will be visiting the Expression

buildStateObjectBuilder

public DefaultConditionalExpressionStateObjectBuilder buildStateObjectBuilder(AbstractConditionalClauseStateObject stateObject)

Creates a builder that can create a conditional expression programmatically. Once the expression is complete, IConditionalExpressionStateObjectBuilder.commit() will push the result onto the given state object.

Parameters:

stateObject - The clause for which a conditional expression can be created

Returns:

The builder of a conditional expression

buildStateObjectBuilder

public DefaultSelectExpressionStateObjectBuilder buildStateObjectBuilder(SelectClauseStateObject stateObject)

Creates a builder that can create a select expression programmatically. Once the expression is complete, ISelectExpressionStateObjectBuilder.commit() will push the result onto the given state object.

Parameters:

stateObject - The clause for which one or many select expressions can be created

Returns:

The builder of a conditional expression

buildStateObjectBuilder

public DefaultSimpleSelectExpressionStateObjectBuilder buildStateObjectBuilder(SimpleSelectClauseStateObject stateObject)

Creates a builder that can create a single select expression programmatically. Once the expression is complete, ISimpleSelectExpressionStateObjectBuilder.commit() will push the result onto the given state object.

Parameters:

stateObject - The clause for which a select expression can be created

Returns:

The builder of a conditional expression

buildStateObjectBuilder

public INewValueStateObjectBuilder buildStateObjectBuilder(UpdateItemStateObject stateObject)

Creates a builder that can create a new value expression programmatically. Once the expression is complete, INewValueStateObjectBuilder.commit() will push the result onto the given state object.

Parameters:

stateObject - The parent for which a new value expression can be created

Returns:

The builder of a new value expression

getGrammar

public JPQLGrammar getGrammar()

Returns the JPQLGrammar that is associated with this builder.

Returns:

The JPQLGrammar that was used to parse the JPQL query or JPQL fragments

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
