Public Methods
public static byte[] loadByteFromFile (Context context, String filePath)
Loads a binary file from the asset folder.
Parameters
| context | Application context to access assets. |
|---|---|
| filePath | Asset path of the file. |
Returns
- the byte array for the binary file.
Throws
public static List < String > loadLabels (Context context, String filePath)
Loads labels from the label file into a list of strings.
A legal label file is the plain text file whose contents are split into lines, and each line is an individual value. The file should be in assets of the context.
Parameters
| context | The context holds assets. |
|---|---|
| filePath | The path of the label file, relative with assets directory. |
Returns
- a list of labels.
Throws
public static List < String > loadLabels ( InputStream inputStream)
Loads labels from an input stream of an opened label file. See details for label files in loadLabels(Context, String)
.
Parameters
Returns
- a list of labels.
Throws
public static List < String > loadLabels ( InputStream inputStream, Charset cs)
Loads labels from an input stream of an opened label file. See details for label files in loadLabels(Context, String)
.
Parameters
| inputStream | the input stream of an opened label file. |
|---|---|
| cs | Charset
to use when decoding content of label file. |
Returns
- a list of labels.
Throws
public static List < String > loadLabels (Context context, String filePath, Charset cs)
Loads labels from the label file into a list of strings.
A legal label file is the plain text file whose contents are split into lines, and each line is an individual value. The empty lines will be ignored. The file should be in assets of the context.
Parameters
| context | The context holds assets. |
|---|---|
| filePath | The path of the label file, relative with assets directory. |
| cs | Charset
to use when decoding content of label file. |
Returns
- a list of labels.
Throws
public static MappedByteBuffer loadMappedFile (Context context, String filePath)
Loads a file from the asset folder through memory mapping.
Parameters
| context | Application context to access assets. |
|---|---|
| filePath | Asset path of the file. |
Returns
- the loaded memory mapped file.
Throws
public static List < String > loadSingleColumnTextFile (Context context, String filePath, Charset cs)
Loads a vocabulary file (a single-column text file) into a list of strings.
A vocabulary file is a single-column plain text file whose contents are split into lines, and each line is an individual value. The file should be in assets of the context.
Parameters
| context | The context holds assets. |
|---|---|
| filePath | The path of the vocabulary file, relative with assets directory. |
| cs |
Returns
- a list of vocabulary words.
Throws
public static List < String > loadSingleColumnTextFile ( InputStream inputStream, Charset cs)
Loads vocabulary from an input stream of an opened vocabulary file (which is a single-column text file).
A vocabulary file is a single-column plain text file whose contents are split into lines, and each line is an individual value. The file should be in assets of the context.
Parameters
| inputStream | the input stream of an opened vocabulary file. |
|---|---|
