Constructor Detail

CustomFunction

public CustomFunction(java.lang.String name)

Construct a new CustomFunction with given name.

Parameters:

name - Name of the function.

Method Detail

getName

public java.lang.String getName()

Gets the name of CastorFunction.

Returns:

The name of CastorFunction.

getParameters

public java.util.List<Expression> getParameters()

Gets the list of parameter expressions of CastorFunction.

Returns:

The list of parameter expressions of CastorFunction.

setParameters

public void setParameters(java.util.List<Expression> parameters)

Sets the list of parameter expressions of CastorFunction.

Parameters:

parameters - The list of parameter expressions of CastorFunction.

toString

public java.lang.StringBuilder toString(java.lang.StringBuilder sb)

Append a string representation of the object to the given StringBuilder. In general, the toString method for query objects appends a string that textually represents this object. The result should be a query string that complies to EJB QL specification as long as the query object represents a syntay element of it. It is required that all subclasses override this method. The toString method defined at class Object is overwritten and calls this method.

Parameters:

sb - StringBuilder to append the string representation of this object to.

Returns:

Same instance of StringBuilder given as parameter.
