Method Detail

setHint

public void setHint(String key,
                    Object value)

Setting hints on this configuration is treated specially if the given key is a target hint.

Specified by:

setHint in interface FetchConfiguration

Overrides:

setHint in class FetchConfigurationImpl

Parameters:

value - if the given key is target hint, then the value can be either null, a String or a non-zero sized String array. It can not be a zero-sized String array.

setHint

public void setHint(String key,
                    Object value,
                    Object original)

Specified by:

setHint in interface FetchConfiguration

Overrides:

setHint in class FetchConfigurationImpl

setTargets

public void setTargets(String[] targets)

isExplicitTarget

public boolean isExplicitTarget()

Affirms if the target is set on this receiver explicitly (i.e. by the user).

toSliceNames

String[] toSliceNames(Object o,
                      boolean user)

assertTargets

void assertTargets(String[] targets,
                   boolean user)

newInstance

protected TargetFetchConfiguration newInstance(FetchConfigurationImpl.ConfigurationState state)

Overrides:

newInstance in class JDBCFetchConfigurationImpl
