Constructor Detail

ImageValueSemanticsProviderAbstract

public ImageValueSemanticsProviderAbstract(FacetHolder holder,
                                   Class<T> adaptedClass,
                                   IsisConfiguration configuration,
                                   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)

Overrides:

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(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 Facet

Overrides:

alwaysReplace in class ValueSemanticsProviderAndFacetAbstract<T>

getUnderlyingFacet

public Facet getUnderlyingFacet()

Description copied from interface: Facet

Underlying Facet of the same type, if any.

Specified by:

getUnderlyingFacet in interface Facet

Overrides:

getUnderlyingFacet in class FacetAbstract

setUnderlyingFacet

public void setUnderlyingFacet(Facet underlyingFacet)

Not required because alwaysReplace() is false.

Specified by:

setUnderlyingFacet in interface Facet

Overrides:

setUnderlyingFacet in class FacetAbstract

isDerived

public boolean isDerived()

Description copied from interface: Facet

Whether this facet implementation is derived (as opposed to explicit); used to determine precedence.

For example, we might derive the typical length of a property based on its type; but if the typical length has been explicitly specified using an annotation then that should take precedence.

Specified by:

isDerived in interface Facet

Overrides:

isDerived in class FacetAbstract

restoreFromByteArray

public T restoreFromByteArray(byte[] byteArray)

doEncode

protected String doEncode(Object object)

Description copied from class: ValueSemanticsProviderAndFacetAbstract

Hook method to perform the actual encoding.

Specified by:

doEncode in class ValueSemanticsProviderAndFacetAbstract<T>

createImage

protected Image createImage(int[][] pixels)

getIconName

public String getIconName()

getPixels

protected abstract int[][] getPixels(Object object)

grabPixels

protected int[][] grabPixels(Image image)

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

protected abstract T setPixels(int[][] pixels)

setMask

public void setMask(String mask)

titleString

public String titleString(Object value,
                 org.apache.isis.applib.profiles.Localization localization)

Description copied from class: ValueSemanticsProviderAndFacetAbstract

Return a string representation of aforesaid object.

Specified by:

titleString in class ValueSemanticsProviderAndFacetAbstract<T>

titleStringWithMask

public String titleStringWithMask(Object value,
                         String usingMask)

Specified by:

titleStringWithMask in class ValueSemanticsProviderAndFacetAbstract<T>

getFacetHolder

public FacetHolder getFacetHolder()

Description copied from interface: Facet

The holder of this facet.

Specified by:

getFacetHolder in interface Facet

Overrides:

getFacetHolder in class FacetAbstract

Returns:

setFacetHolder

public void setFacetHolder(FacetHolder facetHolder)

Description copied from interface: Facet

Allows reparenting of Facet.

Used by Facet decorators.

Specified by:

setFacetHolder in interface Facet

Overrides:

setFacetHolder in class FacetAbstract

toString

public String toString()

Overrides:

toString in class FacetAbstract
