Class FunctionParameter

java.lang.Object
  com.metamatrix.query.function.metadata.FunctionParameter

All Implemented Interfaces:

java.io.Serializable

public class FunctionParameter
extends java.lang.Object
implements java.io.Serializable

A function parameter defines the name and description of an input or output parameter for a function. The name should not be null, but that is not verified by this class. Validation of this object can be done with the FunctionMetadataValidator. The type string used in the function parameter should be one of the standard type names defined in DataTypeManager.DefaultDataTypes.

hashCode

public int hashCode()

Return hash code for this parameter. The hash code is based only on the type of the parameter. Changing the type of the parameter after placing this object in a hashed collection will likely cause the object to be lost.

Overrides:

hashCode in class java.lang.Object

Compare with other object for equality. Equality is based on whether the type is the same as the other parameter.

Overrides:

equals in class java.lang.Object

Returns:

True if equal to obj

toString

public java.lang.String toString()

Return string version for debugging purposes

Overrides:

toString in class java.lang.Object

Returns:

String representation of function parameter

setVarArg
