Class BindingsTemplate

java.lang.Object

io.nosqlbench.virtdata.core.bindings.BindingsTemplate

public class BindingsTemplate
extends Object

Maps a set of parameters on an associated object of type T to specifiers for data mappers. Allows for easy construction of DataMapperBindings when in the proper thread scope.

The user is required to call @{link resolveBindings} when in the scope that the resulting bindings will be used in.

Method Details

addFieldBindings

public void addFieldBindings(List<BindPoint> bindPoints)

addFieldBinding

public void addFieldBinding(String bindPointName,
 String genSpec)

Add a named binding specifier to the template

Parameters:

bindPointName - the name associated with the binding specifier

genSpec - the binding specifier

addFieldBindings

public BindingsTemplate addFieldBindings(Map<String,String> bindPairs)

Add multiple named bindings to the template

Parameters:

bindPairs - A map of named binding specifiers

getDiagnostics

public String getDiagnostics()

resolveBindings

public Bindings resolveBindings()

Use the data mapping library and the specifier to create instances of data mapping functions. If you need thread-aware mapping, be sure to call this in the proper thread. Each time this method is called, it creates a new instance.

Returns:

A set of bindings that can be used to yield mapped data values later.

getBindPointNames

public List<String> getBindPointNames()

getDataMapperSpecs

public List<String> getDataMapperSpecs()

toString

public String toString()

Overrides:

toString in class Object

toString

public String toString(Object[] values)

getMap

public Map<String,String> getMap()
