Method Details

isPredicate

public boolean isPredicate()

Description copied from interface: SqmFunctionDescriptor

Whether the function renders as a predicate.

generateSqmFunctionExpression

protected <T> SelfRenderingSqmFunction<T> generateSqmFunctionExpression(List<? extends SqmTypedNode<?>> arguments,
 @Nullable
 ReturnableType<T> impliedResultType,
 QueryEngine queryEngine)

Description copied from class: AbstractSqmFunctionDescriptor

Return an SQM node or subtree representing an invocation of this function with the given arguments. This method may be overridden in the case of function descriptors that wish to customize creation of the node.

Overrides:

generateSqmFunctionExpression in class AbstractSqmSelfRenderingFunctionDescriptor

Parameters:

arguments - the arguments of the function invocation

impliedResultType - the function return type as inferred from its usage

render

public void render(SqlAppender sqlAppender,
 List<? extends SqlAstNode> sqlAstArguments,
 ReturnableType<?> returnType,
 SqlAstTranslator<?> walker)

Specified by:

render in interface FunctionRenderer

Overrides:

render in class AbstractSqmSelfRenderingFunctionDescriptor

render

protected void render(SqlAppender sqlAppender,
 JsonExistsFunction.JsonExistsArguments arguments,
 ReturnableType<?> returnType,
 SqlAstTranslator<?> walker)
