    • Builder

      protected Builder(int dataSize)
      Constructor. Construct a FontDataTable.Builder with a WritableFontData backing store of size given. A positive size will create a fixed size backing store and a 0 or less size is an estimate for a growable backing store with the estimate being the absolute of the size.
      参数:
      dataSize - if positive then a fixed size; if 0 or less then an estimate for a growable size

    • data

      public WritableFontData data()
      Gets a snapshot copy of the internal data of the builder. This causes any internal data structures to be serialized to a new data object. This data object belongs to the caller and must be properly disposed of. No changes are made to the builder and any changes to the data directly do not affect the internal state. To do that a subsequent call must be made to setData(WritableFontData).
      返回:
      a copy of the internal data of the builder

    • changed

      public boolean changed()
      Determines whether the state of this builder has changed - either the data or the internal model representing the data.
      返回:
      true if the builder has changed

    • notifyPostTableBuild

      protected void notifyPostTableBuild(T table)
      Notification to subclasses that a table was built.

    • subSerialize

      protected abstract int subSerialize(WritableFontData newData)
      Serialize the table to the data provided.
      参数:
      newData - the data object to serialize to
      返回:
      the number of bytes written

    • subReadyToSerialize

      protected abstract boolean subReadyToSerialize()
      返回:
      true if the subclass is ready to serialize it's structure into data

    • subDataSizeToSerialize

      protected abstract int subDataSizeToSerialize()
      Query if the subclass needs to serialize and how much data is required.
      返回:
      positive bytes needed to serialize if a fixed size; and zero or negative bytes as an estimate if growable data is needed

    • subDataSet

      protected abstract void subDataSet()
      Tell the subclass that the data has been changed and any structures must be discarded.

    • subBuildTable

      protected abstract T subBuildTable(ReadableFontData data)
      Build a table with the data provided.
      参数:
      data - the data to use to build the table
      返回:
      a table
