Method Detail

getStore

public FirstRowsExecutionDataSamplerStore getStore()

Specified by:

getStore in class ExecutionDataSamplerStoreBase<FirstRowsExecutionDataSamplerStore>

init

public void init(IVariables variables,
                 IRowMeta inputRowMeta,
                 IRowMeta outputRowMeta)

Description copied from interface: IExecutionDataSamplerStore

Initializes this sampler store

Specified by:

init in interface IExecutionDataSamplerStore

Overrides:

init in class ExecutionDataSamplerStoreBase<FirstRowsExecutionDataSamplerStore>
