Construct a new StringReader with str as source. The size of the reader is set to the length() of the string and the Object to synchronize access through is set to str.
| str | the source string for this reader. |
|---|
Closes this reader. Once it is closed, read operations on this reader will throw an IOException. Only the first invocation of this method has any effect.
Sets a mark position in this reader. The parameter readLimit is ignored for this class. Calling reset() will reposition the reader back to the marked position.
| readLimit | ignored for StringReader instances. |
|---|
| IllegalArgumentException | if readLimit < 0. |
|---|---|
| IOException | if this reader is closed. |
Indicates whether this reader supports the mark() and reset() methods. This implementation returns true.
true. Reads a single character from the source string and returns it as an integer with the two higher-order bytes set to 0. Returns -1 if the end of the source string has been reached.
| IOException | if this reader is closed. |
|---|
Reads at most len characters from the source string and stores them at offset in the character array buf. Returns the number of characters actually read or -1 if the end of the source string has been reached.
| buf | the character array to store the characters read. |
|---|---|
| offset | the initial position in buffer to store the characters read from this reader. |
| len | the maximum number of characters to read. |
| IndexOutOfBoundsException | if offset < 0 or len < 0, or if offset + len is greater than the size of buf. |
|---|---|
| IOException | if this reader is closed. |
Indicates whether this reader is ready to be read without blocking. This implementation always returns true.
true.| IOException | if this reader is closed. |
|---|
Resets this reader's position to the last mark() location. Invocations of read() and skip() will occur from this new location. If this reader has not been marked, it is reset to the beginning of the source string.
| IOException | if this reader is closed. |
|---|
Moves charCount characters in the source string. Unlike the overridden method, this method may skip negative skip distances: this rewinds the input so that characters may be read again. When the end of the source string has been reached, the input cannot be rewound.
| charCount | the maximum number of characters to skip. Positive values skip forward; negative values skip backward. |
|---|
-(num chars already read) <= distance skipped <= num chars remaining.| IOException | if this reader is closed. |
