Method Details

delete

public void delete()

SetMetadata

public int SetMetadata(Hashtable metadata,
 String domain)

Set metadata.

The metadata is set into the domain specified.

Parameters:

metadata - the metadata as a table of (key, value) tuples to apply

domain - the domain of interest. Use "" or null for the default domain.

Returns:

gdalconst.CE_None on success, gdalconst.CE_Failure on failure and gdalconst.CE_Warning if the metadata has been accepted, but is likely not maintained persistently by the underlying object between sessions.

SetMetadata

public int SetMetadata(Hashtable metadata)

Set metadata.

The metadata is set into the default domain

Returns:

gdalconst.CE_None on success, gdalconst.CE_Failure on failure and gdalconst.CE_Warning if the metadata has been accepted, but is likely not maintained persistently by the underlying object between sessions.

Since:

Java bindings 1.7.0

GetDescription

public String GetDescription()

Fetch object description.

The semantics of the returned description are specific to the derived type. For Dataset object it is the dataset name. For Band object it is actually a description (if supported) or "".

Returns:

description

SetDescription

public void SetDescription(String newDescription)

Set object description.

The semantics of the returned description are specific to the derived type. For Dataset object it is the dataset name. For Band object it is actually a description (if supported) or "". Normally application code should not set the "description" for GDALDatasets. It is handled internally.

Parameters:

newDescription - new description

GetMetadataDomainList

public Vector GetMetadataDomainList()

GetMetadata_Dict

public Hashtable GetMetadata_Dict(String domain)

Fetch metadata. Returns metadata as (key, value) tuples in the result table

Parameters:

domain - the domain of interest. Use "" or null for the default domain.

Returns:

null or a hash table with metadata

GetMetadata_Dict

public Hashtable GetMetadata_Dict()

Fetch metadata. Returns metadata from the default domain as (key, value) tuples in the result table

Returns:

null or a hash table with metadata

Since:

Java bindings 1.7.0

GetMetadata_List

public Vector GetMetadata_List(String domain)

Fetch metadata. Returns metadata as a vector of strings of the format "KEY=VALUE".

Parameters:

domain - the domain of interest. Use "" or null for the default domain.

Returns:

null or a vector of strings

GetMetadata_List

public Vector GetMetadata_List()

Fetch metadata.

Returns metadata from the default domain as a vector of strings of the format "KEY=VALUE".

Returns:

null or a vector of strings

Since:

Java bindings 1.7.0

SetMetadata

public int SetMetadata(Vector metadata,
 String domain)

Set metadata.

The metadata is set into the domain specified.

Parameters:

metadata - the metadata to apply as a vector of strings of the format "KEY=VALUE".

domain - the domain of interest. Use "" or null for the default domain.

Returns:

gdalconst.CE_None on success, gdalconst.CE_Failure on failure and gdalconst.CE_Warning if the metadata has been accepted, but is likely not maintained persistently by the underlying object between sessions.

Since:

Java bindings 1.7.0

SetMetadata

public int SetMetadata(Vector metadata)

Set metadata.

The metadata is set into the default domain

Parameters:

metadata - the metadata to apply as a vector of strings of the format "KEY=VALUE".

Returns:

gdalconst.CE_None on success, gdalconst.CE_Failure on failure and gdalconst.CE_Warning if the metadata has been accepted, but is likely not maintained persistently by the underlying object between sessions.

Since:

Java bindings 1.7.0

SetMetadata

public int SetMetadata(String metadataString,
 String domain)

Set metadata.

The metadata is set into the domain specified.

Parameters:

metadataString - the metadata to apply as a string of the format "KEY=VALUE".

domain - the domain of interest. Use "" or null for the default domain.

Returns:

gdalconst.CE_None on success, gdalconst.CE_Failure on failure and gdalconst.CE_Warning if the metadata has been accepted, but is likely not maintained persistently by the underlying object between sessions.

SetMetadata

public int SetMetadata(String metadataString)

Set metadata.

The metadata is set into the default domain

Parameters:

metadataString - the metadata to apply as a string of the format "KEY=VALUE".

Returns:

gdalconst.CE_None on success, gdalconst.CE_Failure on failure and gdalconst.CE_Warning if the metadata has been accepted, but is likely not maintained persistently by the underlying object between sessions.

Since:

Java bindings 1.7.0

GetMetadataItem

public String GetMetadataItem(String name,
 String domain)

Fetch single metadata item.

Parameters:

name - the key for the metadata item to fetch.

domain - the domain to fetch for, use null for the default domain.

Returns:

null on failure to find the key, or the value string on success.

GetMetadataItem
