Class ResourceMetadata

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.HashMap<String,Object>
          org.apache.sling.api.resource.ResourceMetadata

All Implemented Interfaces:

Serializable, Cloneable, Map<String,Object>

public class ResourceMetadata
extends HashMap<String,Object>

The ResourceMetadata interface defines the API for the metadata of a Sling Resource. Essentially the resource's metadata is just a map of objects indexed by string keys.

The actual contents of the meta data map is implementation specific with the exception of the sling.resolutionPath property which must be provided by all implementations and contain the part of the request URI used to resolve the resource. The type of this property value is defined to be String.

Note, that the prefix sling. to key names is reserved for the Sling implementation.

Field Summary

static String	CHARACTER_ENCODING The name of the optional property providing the character encoding of the resource if the resource is streamable and contains character data (value is "sling.characterEncoding").
static String	CONTENT_LENGTH The name of the optional property providing the content length of the resource if the resource is streamable (value is "sling.contentLength").
static String	CONTENT_TYPE The name of the optional property providing the content type of the resource if the resource is streamable (value is "sling.contentType").
static String	CREATION_TIME Returns the creation time of this resource in the repository in milliseconds (value is "sling.creationTime").
static String	MODIFICATION_TIME Returns the last modification time of this resource in the repository in milliseconds (value is "sling.modificationTime").
static String	RESOLUTION_PATH The name of the required property providing the part of the request URI which was used to the resolve the resource to which the meta data instance belongs (value is "sling.resolutionPath").
static String	RESOLUTION_PATH_INFO The name of the required property providing the part of the request URI which was not used to the resolve the resource to which the meta data instance belongs (value is "sling.resolutionPathInfo").

Field Detail

RESOLUTION_PATH

public static final String RESOLUTION_PATH

The name of the required property providing the part of the request URI which was used to the resolve the resource to which the meta data instance belongs (value is "sling.resolutionPath").

See Also:

Constant Field Values

RESOLUTION_PATH_INFO

public static final String RESOLUTION_PATH_INFO

The name of the required property providing the part of the request URI which was not used to the resolve the resource to which the meta data instance belongs (value is "sling.resolutionPathInfo"). The value of this property concatenated to the value of the sling.resolutionPath property returns the original request URI leading to the resource.

This property is optional. If missing, it should be assumed equal to an empty string.

Since:

2.0.4

Constant Field Values

CONTENT_TYPE

public static final String CONTENT_TYPE

The name of the optional property providing the content type of the resource if the resource is streamable (value is "sling.contentType"). This property may be missing if the resource is not streamable or if the content type is not known.

See Also:

Constant Field Values

CONTENT_LENGTH

public static final String CONTENT_LENGTH

The name of the optional property providing the content length of the resource if the resource is streamable (value is "sling.contentLength"). This property may be missing if the resource is not streamable or if the content length is not known.

Note, that unlike the other properties, this property may be set only after the resource has successfully been adapted to an InputStream for performance reasons.

See Also:

Constant Field Values

CHARACTER_ENCODING

public static final String CHARACTER_ENCODING

The name of the optional property providing the character encoding of the resource if the resource is streamable and contains character data (value is "sling.characterEncoding"). This property may be missing if the resource is not streamable or if the character encoding is not known.

See Also:

Constant Field Values

CREATION_TIME

public static final String CREATION_TIME

Returns the creation time of this resource in the repository in milliseconds (value is "sling.creationTime"). The type of this property is java.lang.Long. The property may be missing if the resource is not streamable or if the creation time is not known.

See Also:

Constant Field Values

MODIFICATION_TIME

public static final String MODIFICATION_TIME

Returns the last modification time of this resource in the repository in milliseconds (value is "sling.modificationTime"). The type of this property is java.lang.Long. The property may be missing if the resource is not streamable or if the last modification time is not known.
