getInstance

static EmptyStructuredConfigProperties getInstance()

getString

@Nullable
public String getString(String name)

Description copied from interface: StructuredConfigProperties

Returns a String configuration property.

Specified by:

getString in interface StructuredConfigProperties

Returns:

null if the property has not been configured

getBoolean

@Nullable
public Boolean getBoolean(String name)

Description copied from interface: StructuredConfigProperties

Returns a Boolean configuration property. Implementations should use the same rules as Boolean.parseBoolean(String) for handling the values.

Specified by:

getBoolean in interface StructuredConfigProperties

Returns:

null if the property has not been configured

getInt

@Nullable
public Integer getInt(String name)

Description copied from interface: StructuredConfigProperties

Returns a Integer configuration property.

If the underlying config property is Long, it is converted to Integer with Long.intValue() which may result in loss of precision.

Specified by:

getInt in interface StructuredConfigProperties

Returns:

null if the property has not been configured

getLong

@Nullable
public Long getLong(String name)

Description copied from interface: StructuredConfigProperties

Returns a Long configuration property.

Specified by:

getLong in interface StructuredConfigProperties

Returns:

null if the property has not been configured

getDouble

@Nullable
public Double getDouble(String name)

Description copied from interface: StructuredConfigProperties

Returns a Double configuration property.

Specified by:

getDouble in interface StructuredConfigProperties

Returns:

null if the property has not been configured

getScalarList

@Nullable
public <T> List<T> getScalarList(String name,
 Class<T> scalarType)

Description copied from interface: StructuredConfigProperties

Returns a List configuration property. Empty values and values which do not map to the scalarType will be removed.

Specified by:

getScalarList in interface StructuredConfigProperties

Parameters:

name - the property name

scalarType - the scalar type, one of String, Boolean, Long or Double

Returns:

a List configuration property, or null if the property has not been configured

getStructured

@Nullable
public StructuredConfigProperties getStructured(String name)

Description copied from interface: StructuredConfigProperties

Returns a StructuredConfigProperties configuration property.

Specified by:

getStructured in interface StructuredConfigProperties

Returns:

a map-valued configuration property, or null if name has not been configured

getStructuredList

@Nullable
public List<StructuredConfigProperties> getStructuredList(String name)

Description copied from interface: StructuredConfigProperties

Returns a list of StructuredConfigProperties configuration property.

Specified by:

getStructuredList in interface StructuredConfigProperties

Returns:

a list of map-valued configuration property, or null if name has not been configured

getPropertyKeys

public Set<String> getPropertyKeys()

Description copied from interface: StructuredConfigProperties

Returns a set of all configuration property keys.

Specified by:

getPropertyKeys in interface StructuredConfigProperties

Returns:

the configuration property keys
