Interface HttpParams

All Known Implementing Classes:

DefaultHttpParams

public interface HttpParams

This interface represents a collection of HTTP protocol parameters. Protocol parameters may be linked together to form a hierarchy. If a particular parameter value has not been explicitly defined in the collection itself, its value will be drawn from the parent collection of parameters.

Method Detail

getDefaults

public HttpParams getDefaults()

Returns the parent collection that this collection will defer to for a default value if a particular parameter is not explicitly set in the collection itself

Returns:

the parent collection to defer to, if a particular parameter is not explictly set in the collection itself.

See Also:

setDefaults(HttpParams)

setDefaults

public void setDefaults(HttpParams params)

Assigns the parent collection that this collection will defer to for a default value if a particular parameter is not explicitly set in the collection itself

Parameters:

params - the parent collection to defer to, if a particular parameter is not explictly set in the collection itself.

See Also:

getDefaults()

getParameter

public Object getParameter(String name)

Returns a parameter value with the given name. If the parameter is not explicitly defined in this collection, its value will be drawn from a higer level collection at which this parameter is defined. If the parameter is not explicitly set anywhere up the hierarchy, null value is returned.

Parameters:

name - the parent name.

Returns:

an object that represents the value of the parameter.

See Also:

setParameter(String, Object)

setParameter

public void setParameter(String name,
                         Object value)

Assigns the value to the parameter with the given name

Parameters:

name - parameter name

value - parameter value

getLongParameter

public long getLongParameter(String name,
                             long defaultValue)

Returns a Long parameter value with the given name. If the parameter is not explicitly defined in this collection, its value will be drawn from a higer level collection at which this parameter is defined. If the parameter is not explicitly set anywhere up the hierarchy, the default value is returned.

Parameters:

name - the parent name.

defaultValue - the default value.

Returns:

a Long that represents the value of the parameter.

See Also:

setLongParameter(String, long)

setLongParameter

public void setLongParameter(String name,
                             long value)

Assigns a Long to the parameter with the given name

Parameters:

name - parameter name

value - parameter value

getIntParameter

public int getIntParameter(String name,
                           int defaultValue)

Returns an Integer parameter value with the given name. If the parameter is not explicitly defined in this collection, its value will be drawn from a higer level collection at which this parameter is defined. If the parameter is not explicitly set anywhere up the hierarchy, the default value is returned.

Parameters:

name - the parent name.

defaultValue - the default value.

Returns:

a Integer that represents the value of the parameter.

See Also:

setIntParameter(String, int)

setIntParameter

public void setIntParameter(String name,
                            int value)

Assigns an Integer to the parameter with the given name

Parameters:

name - parameter name

value - parameter value

getDoubleParameter

public double getDoubleParameter(String name,
                                 double defaultValue)

Returns a Double parameter value with the given name. If the parameter is not explicitly defined in this collection, its value will be drawn from a higer level collection at which this parameter is defined. If the parameter is not explicitly set anywhere up the hierarchy, the default value is returned.

Parameters:

name - the parent name.

defaultValue - the default value.

Returns:

a Double that represents the value of the parameter.

See Also:

setDoubleParameter(String, double)

setDoubleParameter

public void setDoubleParameter(String name,
                               double value)

Assigns a Double to the parameter with the given name

Parameters:

name - parameter name

value - parameter value

getBooleanParameter

public boolean getBooleanParameter(String name,
                                   boolean defaultValue)

Returns a Boolean parameter value with the given name. If the parameter is not explicitly defined in this collection, its value will be drawn from a higer level collection at which this parameter is defined. If the parameter is not explicitly set anywhere up the hierarchy, the default value is returned.

Parameters:

name - the parent name.

defaultValue - the default value.

Returns:

a Boolean that represents the value of the parameter.

See Also:

setBooleanParameter(String, boolean)

setBooleanParameter

public void setBooleanParameter(String name,
                                boolean value)

Assigns a Boolean to the parameter with the given name

Parameters:

name - parameter name

value - parameter value

isParameterSet

public boolean isParameterSet(String name)

Returns true if the parameter is set at any level, false otherwise.

Parameters:

name - parameter name

Returns:

true if the parameter is set at any level, false otherwise.

isParameterSetLocally

public boolean isParameterSetLocally(String name)

Returns true if the parameter is set locally, false otherwise.

Parameters:

name - parameter name

Returns:

true if the parameter is set locally, false otherwise.

isParameterTrue

public boolean isParameterTrue(String name)

Returns true if the parameter is set and is true, false otherwise.

Parameters:

name - parameter name

Returns:

true if the parameter is set and is true, false otherwise.

isParameterFalse

public boolean isParameterFalse(String name)

Returns true if the parameter is either not set or is false, false otherwise.

Parameters:

name - parameter name

Returns:

true if the parameter is either not set or is false, false otherwise.
