      Modifier and Type Method Description
      @NotNull String[] getKeys()
      Returns a string array holding all descriptor keys available for this implementation, both the standard descriptors defined by the string constants in this interface and any implementation-specific descriptors.
      @Nullable Value getValue​(@NotNull String key)
      The value of a single-value descriptor is found by passing the key for that descriptor to this method.
      @Nullable Value[] getValues​(@NotNull String key)
      The value array of a multi-value descriptor is found by passing the key for that descriptor to this method.
      boolean isSingleValueDescriptor​(@NotNull String key)
      Returns true if key is a valid single-value descriptor; otherwise returns false
      boolean isStandardDescriptor​(@NotNull String key)
      Returns true if key is a standard descriptor defined by the string constants in this interface and false if it is either a valid implementation-specific key or not a valid key.
    • Method Detail

      • getKeys

        @NotNull
        @NotNull String[] getKeys()
        Returns a string array holding all descriptor keys available for this implementation, both the standard descriptors defined by the string constants in this interface and any implementation-specific descriptors. Used in conjunction with getValue(String key) and getValues(String key) to query information about this repository implementation.
        Returns:
        a string array holding all descriptor keys.
      • isStandardDescriptor

        boolean isStandardDescriptor​(@NotNull
                                     @NotNull String key)
        Returns true if key is a standard descriptor defined by the string constants in this interface and false if it is either a valid implementation-specific key or not a valid key.
        Parameters:
        key - a descriptor key.
        Returns:
        whether key is a standard descriptor.
      • isSingleValueDescriptor

        boolean isSingleValueDescriptor​(@NotNull
                                        @NotNull String key)
        Returns true if key is a valid single-value descriptor; otherwise returns false
        Parameters:
        key - a descriptor key.
        Returns:
        whether the specified descriptor is multi-valued.
        Since:
        JCR 2.0
      • getValue

        @Nullable
        @Nullable Value getValue​(@NotNull
                                 @NotNull String key)
        The value of a single-value descriptor is found by passing the key for that descriptor to this method. If key is the key of a multi-value descriptor or not a valid key this method returns null.
        Parameters:
        key - a descriptor key.
        Returns:
        The value of the indicated descriptor
      • getValues

        @Nullable
        @Nullable Value[] getValues​(@NotNull
                                    @NotNull String key)
        The value array of a multi-value descriptor is found by passing the key for that descriptor to this method. If key is the key of a single-value descriptor then this method returns that value as an array of size one. If key is not a valid key this method returns null.
        Parameters:
        key - a descriptor key.
        Returns:
        the value array for the indicated descriptor
