AbstractTypeHandler

public interface TypeHandler<JavaType>

A class responsible for rendering a Java type into a byte format suitable for transfer to PCP.

Method Summary

Modifier and Type	Method and Description
int	getDataLength()
MmvMetricType	getMetricType()
void	putBytes(java.nio.ByteBuffer buffer, JavaType value) Render the provided value into the given ByteBuffer for access by PCP.
boolean	requiresLargeStorage()

Method Detail

putBytes

void putBytes(java.nio.ByteBuffer buffer,
              JavaType value)

Render the provided value into the given ByteBuffer for access by PCP. No more than 16 bytes should be written to the buffer, unless you want to overflow into the next metric.

Parameters:

buffer - a ByteBuffer, positioned ready to receive the bytes representing this Java type to PCP

value - the value to be converted

getMetricType

MmvMetricType getMetricType()

Returns:

the MmvMetricType used by PCP to understand the bytes written by putBytes(ByteBuffer, Object)

getDataLength

int getDataLength()

requiresLargeStorage

boolean requiresLargeStorage()
