ResourceMergerItem

public ResourceMergerItem(@NonNull
                          java.lang.String name,
                          @NonNull

                          @Nullable
                          java.lang.String libraryName)

Constructs the object with a name, type and optional value.

Note that the object is not fully usable as-is. It must be added to a ResourceFile first.

Parameters:

name - the name of the resource

namespace - the namespace of the resource

type - the type of the resource

value - an optional Node that represents the resource value.

Method Detail

getType

@NonNull
public com.android.resources.ResourceType getType()

Description copied from interface: ResourceItem

Returns the type of this resource.

Specified by:

getType in interface ResourceItem

getValue

Returns the optional value of the resource. Can be null

Returns:

the value or null.

getValueText

@Nullable
public java.lang.String getValueText()

Returns the optional string value of the resource. Can be null

Returns:

the value or null.

getLibraryName

@Nullable
public java.lang.String getLibraryName()

Description copied from interface: ResourceItem

Returns name of the library which defines this resource, or null for app resources.

The contents of the string depend on the build system used to create the ResourceItems.

Specified by:

getLibraryName in interface ResourceItem

getNamespace

@NonNull
public com.android.ide.common.rendering.api.ResourceNamespace getNamespace()

Description copied from interface: ResourceItem

Returns the of this resource.

Specified by:

getNamespace in interface ResourceItem

getQualifiers

@NonNull
public java.lang.String getQualifiers()

Returns the resource item qualifiers.

Returns:

the qualifiers

getSourceType

@NonNull
public DataFile.FileType getSourceType()

getReferenceToSelf

@NonNull
public com.android.ide.common.rendering.api.ResourceReference getReferenceToSelf()

Description copied from interface: ResourceItem

Returns a ResourceReference that points to this resource.

Specified by:

getReferenceToSelf in interface ResourceItem

getConfiguration

@NotNull
public FolderConfiguration getConfiguration()

Description copied from interface: Configurable

Returns the FolderConfiguration for this object.

Specified by:

getConfiguration in interface Configurable

getKey

@NotNull
public java.lang.String getKey()

Returns a key for this resource. They key uniquely identifies this resource by combining resource type, qualifiers, namespace and name.

If the resource has not been added to a ResourceFile, this will throw an IllegalStateException.

Specified by:

getKey in interface ResourceItem

Returns:

the key for this resource.

Throws:

java.lang.IllegalStateException - if the resource is not added to a ResourceFile

wasTouched

protected void wasTouched()

Hook invoked when the data item has been touched. The default implementation does nothing.

getResourceValue

@NonNull
public com.android.ide.common.rendering.api.ResourceValue getResourceValue()

Description copied from interface: ResourceItem

Returns a ResourceValue built from parsing the XML for this resource. This can be used to inspect the value of the resource.

The concrete type of the returned object depends on ResourceItem.getType().

Specified by:

getResourceValue in interface ResourceItem

Returns:

the parsed ResourceValue or null if there was an error parsing the XML or the XML is no longer accessible (this may be the case in the IDE, when the item is based on old PSI).

isFileBased

public boolean isFileBased()

Description copied from interface: ResourceItem

Returns true if the ResourceItem represents a whole file, not an XML tag within a values XML file. This is the case for e.g. layouts or colors defined as state lists.

Returns a formatted string usable in an XML to use for the ResourceMergerItem.

Parameters:

system - Whether this is a system resource or a project resource.

Returns:

a string in the format @[type]/[name]

compareValueWith

public boolean compareValueWith(ResourceMergerItem resource)

Compares the ResourceItem getValue() together and returns true if they are the same.

Returns the name of the item.

getSource

@Nullable
public F getSource()

Returns the DataFile the item is coming from.

setSource

public void setSource(@Nullable
                      F sourceFile)

Obtains the full status of the data item; should not generally be used except for debug purposes.

Returns:

the internal representation

getFile

@Nullable
public java.io.File getFile()

Returns the File from which this DataItem was created, if known. For some subclasses of DataItem, the file is known even if getSource() returns null.
