ImageValueSemanticsProviderAbstract

public ImageValueSemanticsProviderAbstract(org.apache.isis.core.metamodel.facetapi.FacetHolder holder,
                                           Class<T> adaptedClass,

                                           ValueSemanticsProviderContext context)

Method Detail

getParser

public org.apache.isis.applib.adapters.Parser<T> getParser()

Returns null to indicate that this value does not parse entry strings

Specified by:

getParser in interface org.apache.isis.applib.adapters.ValueSemanticsProvider<T>

Overrides:

getParser in class ValueSemanticsProviderAndFacetAbstract<T>

doParse

protected T doParse(Object original,
                    String entry)

Specified by:

doParse in class ValueSemanticsProviderAndFacetAbstract<T>

Parameters:

original - - the underlying object, or null.

entry - - the proposed new object, as a string representation to be parsed

getAsByteArray

public byte[] getAsByteArray(org.apache.isis.core.metamodel.adapter.ObjectAdapter object)

alwaysReplace

public boolean alwaysReplace()

Description copied from class: ValueSemanticsProviderAndFacetAbstract

We don't replace any (none no-op) facets.

For example, if there is already a PropertyDefaultFacet then we shouldn't replace it.

Specified by:

alwaysReplace in interface org.apache.isis.core.metamodel.facetapi.Facet

Overrides:

alwaysReplace in class ValueSemanticsProviderAndFacetAbstract<T>

getUnderlyingFacet

Overrides:

getUnderlyingFacet in class org.apache.isis.core.metamodel.facetapi.FacetAbstract

setUnderlyingFacet

public void setUnderlyingFacet(org.apache.isis.core.metamodel.facetapi.Facet underlyingFacet)

Not required because alwaysReplace() is false.

Specified by:

setUnderlyingFacet in interface org.apache.isis.core.metamodel.facetapi.Facet

Overrides:

setUnderlyingFacet in class org.apache.isis.core.metamodel.facetapi.FacetAbstract

isDerived

public boolean isDerived()

Specified by:

isDerived in interface org.apache.isis.core.metamodel.facetapi.Facet

Overrides:

isDerived in class org.apache.isis.core.metamodel.facetapi.FacetAbstract

restoreFromByteArray

public T restoreFromByteArray(byte[] byteArray)

doEncode

doRestore

public T doRestore(String data)

Description copied from class: ValueSemanticsProviderAndFacetAbstract

Hook method to perform the actual restoring.

Specified by:

doRestore in class ValueSemanticsProviderAndFacetAbstract<T>

setPixels
