Interface CountMinSketchAgentForge

All Known Implementing Classes:

CountMinSketchAgentStringUTF16Forge

public interface CountMinSketchAgentForge

For use with Count-min sketch aggregation functions: The agent implementation encapsulates transformation of value objects to byte-array and back (when needed), and may override or provide custom behavior.

This is an extension API and may use internal classes. As such the interface may change between versions.

Method Summary

Modifier and Type	Method and Description
com.espertech.esper.common.internal.bytecodemodel.model.expression.CodegenExpression	codegenMake(com.espertech.esper.common.internal.bytecodemodel.base.CodegenMethod parent, com.espertech.esper.common.internal.bytecodemodel.base.CodegenClassScope classScope) Provides the code for the agent.
java.lang.Class[]	getAcceptableValueTypes() Returns an array of types that the agent can handle, for validation purposes.

Method Detail

getAcceptableValueTypes

java.lang.Class[] getAcceptableValueTypes()

Returns an array of types that the agent can handle, for validation purposes. For example, an agent that accepts byte-array type values should return "new Class[] {String.class}". Interfaces and supertype classes can also be part of the class array.

Returns:

class array of acceptable type
