Method Detail

getOutputType

public com.google.common.reflect.TypeToken<NeededCoverageSpec> getOutputType()

Specified by:

getOutputType in interface TypeCoercer<Object,NeededCoverageSpec>

hasElementClass

public boolean hasElementClass(Class<?>... types)

Description copied from interface: TypeCoercer

Returns whether the leaf nodes of this type coercer outputs value that is an instance of the given class or its subclasses. Does not match non-leaf nodes like Map or List.

Specified by:

hasElementClass in interface TypeCoercer<Object,NeededCoverageSpec>

traverse

public void traverse(CellNameResolver cellRoots,
                     NeededCoverageSpec object,
                     TypeCoercer.Traversal traversal)

Description copied from interface: TypeCoercer

Traverse an object guided by this TypeCoercer.

#{link Traversal#traverse} function will be called once for the object. If the object is a collection or map, it will also recursively traverse all elements of the map.

Specified by:

traverse in interface TypeCoercer<Object,NeededCoverageSpec>

getUnconfiguredType

public com.google.common.reflect.TypeToken<Object> getUnconfiguredType()

Specified by:

getUnconfiguredType in interface TypeCoercer<Object,NeededCoverageSpec>

coerceToUnconfigured

public Object coerceToUnconfigured(CellNameResolver cellRoots,
                                   ProjectFilesystem filesystem,
                                   ForwardRelativePath pathRelativeToProjectRoot,
                                   Object object)
                            throws CoerceFailedException

Description copied from interface: TypeCoercer

Coerce to a value for unconfigured graph.

Specified by:

coerceToUnconfigured in interface TypeCoercer<Object,NeededCoverageSpec>

Throws:

CoerceFailedException

coerce

public NeededCoverageSpec coerce(CellNameResolver cellNameResolver,
                                 ProjectFilesystem filesystem,
                                 ForwardRelativePath pathRelativeToProjectRoot,
                                 TargetConfiguration targetConfiguration,
                                 TargetConfiguration hostConfiguration,
                                 Object object)
                          throws CoerceFailedException

Specified by:

coerce in interface TypeCoercer<Object,NeededCoverageSpec>

Throws:

CoerceFailedException - Input object cannot be coerced into the given type.
