Method Detail

fromFile

public final T fromFile(java.io.File file)
                 throws java.io.IOException

Parses a graph config given as JSON file. Relative paths found in JSON are resolved relative to given file.

Parameters:

file - the input file

Returns:

the graph configuration object

Throws:

java.io.IOException - if there was any I/O error during reading given file

fromFilePath

public final T fromFilePath(java.lang.String path)
                     throws java.io.IOException

Parses a graph config given as path to a JSON file. Relative paths found in JSON are resolved relative to given file.

Parameters:

path - the path to the JSON file

Returns:

the graph configuration object

Throws:

java.io.IOException - if there was any I/O error during reading given file

fromInputStream

public final T fromInputStream(java.io.InputStream is)
                        throws java.io.IOException

same as fromInputStream(InputStream, String), but with null passed as parentPath

Parameters:

is - the input stream to read

Returns:

the graph configuration object

Throws:

java.io.IOException - if there was any I/O error during reading given input stream

fromInputStream

public final T fromInputStream(java.io.InputStream is,
                               java.lang.String parentPath)
                        throws java.io.IOException

Parses a graph config given as input stream.

Parameters:

is - the input stream to read

parentPath - if not null, relative paths found in config will resolved against this parentPath

Returns:

the graph configuration object

Throws:

java.io.IOException - if there was any I/O error during reading given input stream

fromJson

public final T fromJson(java.lang.String json)
                 throws java.io.IOException

Same as fromJson(String, String), but with null passed as parentPath.

Parameters:

json - the input JSON string

Returns:

the graph configuration object

Throws:

java.io.IOException - if there was any I/O error during reading given JSON string

fromJson

public final T fromJson(java.lang.String json,
                        java.lang.String parentPath)
                 throws java.io.IOException

Parses a graph config given as JSON string.

Parameters:

json - the input JSON string

parentPath - if not null, relative paths found in config will resolved against this parentPath

Returns:

the graph configuration object

Throws:

fromProperties

public final T fromProperties(java.io.InputStream is)
                       throws java.io.IOException

same as fromProperties(Properties), but instantiates a new Properties object from the given InputStream.

Parameters:

is - the input stream containing graph configuration in Properties format.

Returns:

the graph configuration object

Throws:

java.io.IOException - if there was any I/O error during reading given input stream
