Class InterpolatorFilterReaderLineEnding

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, java.lang.Readable
    public class InterpolatorFilterReaderLineEnding
extends AbstractFilterReaderLineEnding
    A FilterReader implementation, that works with Interpolator interface instead of it's own interpolation implementation. This implementation is heavily based on org.codehaus.plexus.util.InterpolationFilterReader.
    Since:
    1.0

    • Method Detail

      • skip

        public long skip​(long n)
          throws java.io.IOException
        Skips characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached.
        Overrides:
        skip in class java.io.FilterReader
        Parameters:
        n - The number of characters to skip
        Returns:
        the number of characters actually skipped
        Throws:
        java.io.IOException - If an I/O error occurs

      • read

        public int read​(char[] cbuf,
                int off,
                int len)
         throws java.io.IOException
        Reads characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.
        Overrides:
        read in class java.io.FilterReader
        Parameters:
        cbuf - Destination buffer to write characters to. Must not be null.
        off - Offset at which to start storing characters.
        len - Maximum number of characters to read.
        Returns:
        the number of characters read, or -1 if the end of the stream has been reached
        Throws:
        java.io.IOException - If an I/O error occurs

      • read

        public int read()
         throws java.io.IOException
        Returns the next character in the filtered stream, replacing tokens from the original stream.
        Overrides:
        read in class java.io.FilterReader
        Returns:
        the next character in the resulting stream, or -1 if the end of the resulting stream has been reached
        Throws:
        java.io.IOException - if the underlying stream throws an IOException during reading

      • isInterpolateWithPrefixPattern
