Method Detail

getValue

public com.android.resources.Density getValue()

getEnumValue

public com.android.resources.ResourceEnum getEnumValue()

Specified by:

getEnumValue in class EnumBasedResourceQualifier

getName

public java.lang.String getName()

Description copied from class: ResourceQualifier

Returns the human readable name of the qualifier.

Specified by:

getName in class ResourceQualifier

getShortName

public java.lang.String getShortName()

Description copied from class: ResourceQualifier

Returns a shorter human readable name for the qualifier.

Specified by:

getShortName in class ResourceQualifier

See Also:

ResourceQualifier.getName()

since

public int since()

Description copied from class: ResourceQualifier

Returns the API level when this qualifier was added to Android.

Specified by:

since in class ResourceQualifier

checkAndSet

public boolean checkAndSet(java.lang.String value,
                           FolderConfiguration config)

Description copied from class: ResourceQualifier

Check if the value is valid for this qualifier, and if so sets the value into a Folder Configuration.

Specified by:

checkAndSet in class ResourceQualifier

Parameters:

value - The value to check and set. Must not be null.

config - The folder configuration to receive the value. Must not be null.

Returns:

true if the value was valid and was set.

isValid

public boolean isValid()

Description copied from class: ResourceQualifier

Returns whether the qualifier has a valid filter value.

Overrides:

isValid in class EnumBasedResourceQualifier

getNullQualifier

public DensityQualifier getNullQualifier()

Description copied from class: ResourceQualifier

Returns the qualifier that can be used in ResourceQualifier.isBetterMatchThan(ResourceQualifier, ResourceQualifier) when no qualifier is present in the config. null has a special meaning when trying to match the best config (it's the worst qualifier, unless not other alternative matches). If a qualifier type has a different definition of best in regards to the null qualifier, this method should be subclassed and a special value should be returned from here, which can then be used to call (ResourceQualifier, ResourceQualifier) which can implement the custom logic.

Overrides:

getNullQualifier in class ResourceQualifier

isMatchFor

public boolean isMatchFor(ResourceQualifier qualifier)

Description copied from class: ResourceQualifier

Returns whether the given qualifier is a match for the receiver. The default implementation returns the result of ResourceQualifier.equals(Object). Children class that re-implements this must implement (ResourceQualifier, ResourceQualifier) too.

Overrides:

isMatchFor in class ResourceQualifier

Parameters:

qualifier - the reference qualifier

Returns:

true if the receiver is a match.

isBetterMatchThan

public boolean isBetterMatchThan(@Nullable
                                 ResourceQualifier compareTo,
                                 @NonNull
                                 ResourceQualifier reference)

Description copied from class: ResourceQualifier

Returns true if the receiver (this) is a better match for the given reference than the given compareTo comparable.

Overrides:

isBetterMatchThan in class ResourceQualifier

Parameters:

compareTo - The ResourceQualifier to compare to.

reference - The reference qualifier value for which the match is (from phone's folderConfig).
